and retention times of known metabolites. This table needs
columns mz_calc for the mz value calculated from the mass of the isotope,
rtmin, rtmax for the retention time window where the peak is expected
to elute from the column in order to restrict the match of the table against
the ``mz_reference_table`.

destination is a directory which will be used for storing the
result and intermediate data. If you do not specify this value, a
